T all 'whom t may concern.'

Be it known that I, Vieron 1V. PAG, a citizen of the United States, and a resident of the city ot New York, Kew Gardens, borough of Queens, in the county of Queens and State 'of New York, have invented a new and Improved Oil-Sump Screen, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in internal combustion notors, and it pertains more particularly to a screen construction for straining the lubricating oil before the` same is introduced to the oil-circulating pump.

It is one of the objects' of the invention to construct ascreen in such a manner that the same may be entirely removed to facilitate the cleaning thereof.

It is a. further object of the invention to provide means whereby the screen may be bodily removed without necessitating the draining ot' the lubricant from the crank case.

It is a still further object of the invention to provide a new and novel form of operating means for operating the oil-controlling means.

Tith the above and other objectsvin view, 30 reference is had to the accompanying drawings, in which- Figure 1 is a vert-ical sectional view of a screen constructed in accordance with the present invention; l

Fig. 2 is a horizontal sectional view partly broken away of the device in one position, and

F ig. 3 is a horizontal sectional view of the device in its other or closed position.

Referring more particularly to the draw-v ings, the reference character 5 designa-tes the bottom wall of a motor crank case, and said bottom wall is provided with an opening 6 of any desired shape. The reference char- 45 acter 7 designates a plate and said plate is of a size suiiicient to close the opening 6 in the bottom wall of the crank case and is adapted to be secured to the crank case by means of bolts or the like 8.

50 This plate 7 is provided with a central cylindrical portion 10 depending from said plate 7 to form an oil receptacle 11. Secured in one of the sides of the depending portion 10, is a nipple 12, and leading from 552 said nipple 12 t0 an oil pump (not shown) is a pipe 13. The plate 10 is provided with a flange 14, as indicated by the reference character 15.Y

Adapted for threaded engagementwith the ange 14, is a vertically projected tubular member 16, and said tubular member 16 has its upper edge dened by a flange 17. This tubular member 16 is provided with a. plurality of cut-out portions 18 extending throughout the major portion of its length in order that the oil contained in the crank case may flow through the said cut out portions to the oil receptacle 11. Surrounding thetubular member 16 is a sleeve 20, and said sleeve 2O is provided with a plurality of cut-out port-ions 21 adapted to register with the cut-out portions 18 in the tubular member 16 in order that said oil may flow to the receptacle 11 when these cut-out portions are in registry. The sleeve 2O is adapted for rotation about the tubular member 16, and to provide for this, rot-ation the said sleeve 20 is provided on its lower end with a plurality of teeth 24 meshing with the teeth 25 of a small gear wheel 26. This small gear wheel 26 is carried by a shaft 27 mounted in a lug 28 depending from the lower face of the plate 7 and said shat't 27 is provided with an operating handle 29, by means of which the shaft 27 and its gear 26 may be rotated.

Thereference character 30 designates a screen and said screen is carried by av metallic sleeve 31 adapted to fit in the depending portion 10 of the plate 7. This sleeve 31 is provided with an opening 32 adapted to register with the passage through the nipple 12 in order that communication may be established between the pipe 13 and the receptacle 11.

The lower end of the depending portion 10 is threaded as indicated at 33, and having threaded engagement with this threaded portion of the depending member 10, is a plug 34, which plug is adapted to close the open lower end of the member 10. As indica-ted by the reference character 35, the sleeve 31 is flared outwardly by the plug 341 in order that a tight joint between the sleeve 31, the member 10 and the plug 34: may be had. The plug 34 is provided with any suitable tool connection 36 in order that the same may be operated.

The device operates in the following manner: With the parts in the position shown and said-Harige 14 is threaded in Fig. 1, it is apparent that a free circulation of oil may be had from the interior ot the crank case through the registering openings 18 and 21 of the-tubularmember 16, and the sleeve 20, respectively, to the receptacle 11, From the receptacle 11, the oil passes through the openin 32 through the nipple 12 to the pipe line 13 under the 'influenee oit a pump (not shown) Then it is desired to remore the screen for the purpose of cleaning the same, `the operating handle 29 is moved ton rotate the shaft 2T untilthe cut-out portions 21 ot the sleeve 2O pass out of registry `:with the cutout portions 18 of the tubular member 16, which position of parts is shown in i vWith the parts in this position it .is apparent that the flow ot' oil Jfrom the crank case to the receptacle is cut oli. After this flow ot oil has b en cnt oli' as above described`r it is onlyv necessary to remore the plug 34 after which the screen 30 mayY be removed and cleaned, After the screen has been cleaned it is replaced and the plug- 3l is positioned, after which the openings 1S and 21 are moved into registry, in which position a tree circulation ot oil is had.

From the foregoing it is apparent that the screen 3G may be removed for the purposes ot cleaning Without necessitating any great Waste of oil since the volume of oil lost upon removal of the screen 30 is onlyY that which is contained Within the receptacle 11 and the tubular member 15, which amount is negligible as compared to the bulli.

I claim: V A

ln an engine snmp, a stationary plate provided with passage extending therethrough, a slotted tubular member surrounding` said passage and projecting inwardly of the sump5 a slotted sleeve 'surounding `Said slotted tubular member and movable with respect thereto, a sleeve slidablyv mounted in the opening ot' said plate, means for retaining said sleeve in position in the openingv in said plate, and a. screen carried by said sleeve and projecting inwardlyot the sump Within the contines ot the slotted tubular member.
